I maxed out my king at Th7 pretty quickly because when upgrading to TH6, I took my bum to Crystal in hope for 2k+ DE drill raids.

DE Drills are the main source. DE is only generated in three possible ways Drills, League Bonus and War Bonus. The majority of DE gets generated by drills. Raiding apart from the League Bonus doesn't generate any new DE you're simply taking someone elses DE.
People only think about it from their own perspective TH7 can get a level 3 drill that's only 45 DE an hour and doesn't seem like much, but multiply that by the thousands of th7s out there and that's how much DE production was added to a TH level that produced nearly zero DE before and TH8s doubled their production as-well.
I'm level 81 currenlty with Town Hall level 8 and i get 1000 DE from drills daily and approx 5000 from raids so i think that they aren't the main source, they are just a help, just a bit.
PS : your calculations are accurate, there was a lot of DE added to Town Hall 7 level.
Yea of course that i comes from another Dark Elixir Drill, but someone above me said that DE drill at town hall 7 will make it a lot easier, in 2 week you can gather your DE for barbarian king so i wanted to tell him that most of the dark elixir comes from raids and bonus.
